Application filed January 26,1926. Serial No. 83,849.

The present invention relates to certain new and useful improvements in window screen. constructions and among the objects of my invention are the following 6 To provide a screen which may be easily and cheaply made and which'will be of last ing duration.

To provide a screen in which the vframe of the screen holds the screen taut so' as to pre- 10 vent wrinkling or looseness.

rolled dull edge and a clamping means by which the screen cloth is held so that bolts,

screws 01" the like are not necessary in holding the screen material in place.

To afford an integral screen frame having a smooth surface with no protruding bolts or parts so that two screens may slide against each other without obstruction, thus providing efficient extensible screens.

A further .object of my invention is to provide an efiicient means for holding the screen cloth to the frame in which a clamping memberpressed against the rolleddull edge on four edges of the molding to force the same into position to hold the screen cloth securely in place, and such other ad-' vantages, objects and capabilities as will later more fully appear.

My invention further resides in the construction, combination and arrangement of -parts illustrated in the accompanying draw lugs, and while I have shown therein a preferred embodiment of my invention, I Wish I 36 it understood that the same is susceptible of modification and change without departing fromthe spiritof my invention.

Referring to the drawings, Fig.1 1s a ver- 1 tical transverse section through a portion of 40' a window showing my improved screen applied thereto.

- Fig. 2 is a perspective view also'showing in vertical transverse section an end portion of 'my screen.

I Fi 3 is a cross-section through one side of t e frame of my. screenshowing the screen mesh in place prior'to pressing the frame portion into completed position.

Fig. 4 is. a similar view after the partsin J0 Fig. 3 have been pressed into completed -form to bind the screen in place, on all-four sides simultaneously. v

Fig. 5' is a vertical transverse section throughjthelower portion of the window- 'formed'in the other member.

' Fig. 8 is a front elevation of the sliding screen shown in Fig. 7 To prov1de a metal molding having a My invention more in detail comprises a molding or frame 1 formed with .a flat rolled dull edge 3- and a clamping member or..1eg 4. In assembling, the screen-cloth 2 is placed over the rolled dull edge 3 of the molding land is inserted into the molding a suitable distance as clearly shown in Fig. 3. The leg 4 is then pressed down against the rolled dull edge 3 by any suitable pressing means so as to hold the screen cloth 2 securely in place as clearly shown in Fig. 4. This means of holding the screen-cloth in. place is a plicity an efliciency. The screen cloth is rendered taut as a result of the pressing and cannot be, loosened by ordinary wear. I

have eliminated the need for clamps, bolts v or the like so that the surface of the frame is smooth and unobstructed. This smooth surface of the frame makes practical the use of my invention in extensible screens 5 slidable on each other as shown in Figs. 5, 6, 7

and, 8, in which flanged lugs 6 formed on one of the frame-members slide in slots 7 for slidably connecting these partsmaybe used ifdesired.

Having now described my invention, Iclaim: f 15A screen construction compris' tegral framecomposed of 'a single s set of metal bent upon Itself to form a flatback and side portions, saidside portions bein parallel throughout their length, the. end 0 great improvement dye to its Sim-- Other means:

an inone side provided with :1. rolled dull edge and the end of the other side provided with a lateral projection for clamping the screen between said edge and projection.

'2. A screen construction comprising an in-' a lateral pro ection for clamplng and hold 20 mg taut a screen between said edge and protegral frame formed to provide fiat back and side portions, said side portions-being parallel throughout their length, the end of one side provided. with :1 rolled dull edge and the end of the other side provided-with a clamping member adapted to grip and hold taut a screen member.

3. A screen construction comprising an integral frame composed of a single sheet of metal bent upon itself 'tovform' a flat back 15 and side portions, said back portionsbeing vparallel throughout their-length, the end of one side provided with a rolled dull edgeand the end of the other side rovided with jection, the edge of said projection forcing said screen against the opposite side of the frame member.

In'witness whereof, I hereunto subscribe 25 my name to this specification- FRANCIS J. PLYM.
